Description

[Detailed description of the invention] This invention relates to an attic ventilation system.

BACKGROUND ART Conventionally, some buildings in snowy regions have adopted a so-called snow duct type roof in which a snow catcher is provided on a roof panel and water from melting snow is utilized. However, in such buildings,
Because the attic space located between the snow catcher and the roof panel is not sufficiently ventilated, condensation occurs within the attic space, shortening the lifespan of the building. On the other hand, in order to prevent this, it may be possible to install a ventilation louver or the like, but this raises another problem of high equipment costs.

Therefore, the object of this invention is to provide an attic ventilation system that can perform attic ventilation at low cost.

An embodiment of this invention will be described with reference to FIGS. 1 to 3. That is, as shown in FIG. 1, in this attic ventilation system, a snow catcher 4 is formed by the roof panels 2 and 3 above the roof panel 1, and the roof panel 3 is tilted downward toward the center. By forming the water outlet 5 at the lower end of the slope,
This is applied to a so-called snow duct type roof in which water from melting snow in the snow catcher 4 is taken out from the water outlet 5 and used, and is an attic space surrounded by the roof panel 1 and the roof plates 2 and 3. This is for ventilation of 6.

Figure 2 shows an enlarged sectional view of the eave structure. As shown in the figure, a roof panel 1 consisting of a panel frame 1a and a surface plate 1b is mounted on the upper end of a wall panel 7 via a spacer 8, and a fascia 9 is attached to the tip of the eave of this roof panel 1. Connected flush with the outdoor surface board 7a of the wall panel 7, a base material 10 is laid along the top edge of the eaves of the roof panel 1, and a projecting piece 11b is integrally projected from the lower end of the vertical side of the inverted L-shaped piece 11a. A draining plate 11 having the same configuration as above is fixed with the tip of the horizontal side of the inverted L-shaped piece 11a along the upper surface of the base material 10, and the tip of the protruding piece 11b is connected to the outdoor surface of the fascia 9. On the other hand, a horizontal member 12 is laid on the upper surface of the roof panel 1 in parallel to the base material 10, and a plurality of bundles 13 are intermittently erected on the upper surface of the horizontal member 12.
The roof base material 14 is placed between the upper parts of the bundle 13 and the draining board 11, respectively.
6 is attached, the roof base material 17 is stretched between these horizontal members 15 and 16 in an inclined state, the roof board 2 is fixed along the roof base materials 17 and 14, and one end thereof is connected to the draining board 11. At the same time, the other end is placed at the rear of the bundle 13. Furthermore, by bridging the roof base material 18 between the upper parts of the bundle 13 and connecting one end of the roof shingle 3 to this roof base material 18, ventilation can be provided between one end of the roof shingle 3 and the other end of the roof shingle 2. Mouth 1
form 9.

In this case, as shown in FIG. 3, a plurality of notches 10a are intermittently formed in the upper surface of the base material 10 along the longitudinal direction, and an inverted L-shaped piece of the drain plate 11 is placed on the base material 10. A ventilation opening 20 (see FIG. 2) is formed by connecting the ends of the lateral sides of 11a.
Further, a ventilation hole 21 is also formed in advance on the protruding piece 11b of the draining plate 11.

As a result of this configuration, the attic space 6 is communicated with the outdoors through the ventilation holes 20 and 21, and also communicated with the outside through the ventilation hole 19. You can ventilate the attic. Moreover, since the ventilation holes 20 and 21 are formed intermittently in large numbers along the eaves of the building, and the ventilation holes 19 are continuously formed parallel to the eaves,
The amount of ventilation is large, and moisture does not accumulate in the corners of the attic space 6. In addition, the ventilation holes 20 and 21 are constructed using conventional construction materials such as a base material 10 and a drain plate 1.
Since it is formed by processing 1, it is finished at a low price.

In addition, instead of the base material 10, as shown in FIG. 4, a plurality of block materials 22 are intermittently installed on the roof panel 1, and
These block materials 22 are placed on top of the horizontal material 23.
The base material 24 may be composed of the horizontal material 23 and the horizontal material 23 . In this case, the space surrounded by the roof panel 1, the block members 22 and the cross members 23 forms the ventilation opening 25. In addition, the base material 10 shown in FIG. 3 is turned over, and the roof panel 1 is placed with the notch 10a facing downward as shown in FIG.
It can also be installed on top. In this case, the cutout 10a forms the ventilation opening 26.

As mentioned above, the attic ventilation system of this invention is
A roof panel, a fascia attached to the edge of the eaves of this roof panel, a base material laid along the top edge of the eaves of the roof panel, and a side edge of the inverted L-shaped piece placed along the top surface of the base material. a draining board whose longitudinal side is arranged in front of the fascia and whose tip is integrally protruded rearward from the lower end of the longitudinal side and which is connected and fixed to the outdoor surface of the fascia; and the draining board. In an eaves structure comprising a sloped roof board that rises upward from the base end of the horizontal side to form an attic space between the roof panel and the roof panel, a first ventilation opening is formed in a protrusion of the drain board. In addition, since a second ventilation opening is formed in the base material and both ventilation openings communicate the attic space with the outdoors, there is an effect that attic ventilation can be performed at a low cost.
